Gasterosteus aculeatus      DSP/PTEN


※ PTEN family introduction

    PTEN (phosphatase and tensin homolog deleted on chromosome ten) phosphatase is a conserved family of DUSP phosphatase, which could dephosphorylate tyrosine-, serine- and threonine-phosphorylated proteins. PTEN also acts as lipid phosphatase, which dephosphorylates D3-phosphorylated inositol phospholopids (1). PTEN negatively regulates PI3 kinase-Akt signaling pathway by converting second messenger phosphatidylinositol 3,4,5-triphosphate (PIP3) into phosphatidylinositol 4,5-bisphosphate (PIP2). This pathway plays an important role in controlling cell proliferation, growth and survival (2). In addition to its dominant inhibitory activity in the PI3 kinase-Akt pathway, PTEN also possess potential protein phosphatase activity for its sequence similarity with PTP domain and this remains more understood.
